SPECIFICATION forming part of Letters Patent No. 676,048, dated June 11, 1901.

` Application led October 11,1900. Serial No. 821765. (No model.)

To all whom it may concern:

Be it known that I, CORWIN T. PRICE, a citizen of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Machines for Filling Seed Bags or Packets; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. l

This invention relates to new and useful improvements in machines for filling bags, and especially to a mechanism for automaticallyfilling seed-bags and pasting the flap after being filled.

Theinvention will be hereinafter more fully described, and then specifically defined in the appended claims, and is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form part of this application, and in which drawings similar letters of reference indicate like parts throughout the several views, in which- Figure 1 is a vertical central sectional view through my improved bag-lling machine, parts of the device being shown in elevation. Fig. 2 is a similar View showing the operative parts of the machine in slightly different relation than in Fig. 2, said figure showing the positions that the various operative parts of the machine assume in the second step of the filling operation of the bags. Fig. 3 is an end elevation of the machine. Fig. 4 is a detail sectional view showing the relative positions of the bag-filling tube and the rack holding the bag, the parts being shown in their proper relative positions before the bag is filled. Fig. 5 is a similar view showing the second step in the filling operation of the bags, said figure showing a bag-filling tube depressed into a bag. Fig. 6 is a similar view showing the next step in the filling operation, said figure showing the bag filled and held by means of a clamping member. Fig. 7 is a view showing the bag heldclosed by a'clamping member and the flap of the bag folded.

Fig. 8 is a detail view showing the next step in the operation, in which the bag is held by a clamping member and the folding member in operation, said view showing the bag held by a carriage in an advance relation to that assumed in Fig. 4 of the drawings. Fig. 9 is a detail sectional view showing the flap folded against the bag. Fig. 10 is a detail view showing the bag as folded and the clamping member withdrawn from the bag. Fig. 1l is a detail view showing the bag as having been pasted and .folded and dropping from the machine. Fig. 12'is an enlarged detail in perspective of the carriage which carries the filled bags forward. Fig. 13 is an enlarged detail view, partly in section, of the telescoping members, which are spring-actuated for the purpose of holding the bag before it is advanced to have its iap pasted and sealed. Fig. 14 is an enlarged detail in perspective of the flap-turning member, and Fig. l5 is an end elevation in detail of the rack carrying the empty sacks.

Reference now being had to the details of the drawings by letter, A designates the plat'- form of the machine, which is supported on suitable legs A. Rising from said platform are the upright posts A", which have a crosspiece A3 at their upper ends, said cross-piece being apertured at A4 to allow seed to fall into the upper filling end of the tube or chute B. Mounted on the cross-piecel A3 is a hopper A, and sliding under said hopper in the space intervening between the outlet end of said hopper and the upper face of the crosspiece is a block A5, which is apertured at A6. This block is provided for the purpose of carrying a sufficient quantity of seed from the hopper to a location over the upper fiaring end of the tube or chute B, from which the seed fall by gravity into the bag directly underneath the bottom of said tube. The main operating-shaft C is mounted in suitable bearings C', and journaled to a crank C, formed out of said shaft, is a link C, which has pivotal connection at its outer end to the lower end of the lever D at D. Said lever D has pivotal connection with one of the uprights A2 on the pivot a. (Shown clearly in Figs. 1 and 2 of the drawings.) The upper end of said lever D has pivoted thereto a link D, which at its opposite end is pivoted to the slide A5 by means of a pivot D3, whereby as said lever D is rocked on its pivot a the seed-feeding slide A"s is reeiprocated back and forth on the cross-piece A3.

Mounted about and telescoping over the tube B is a tubing E, the lower end of which is tapered or beveled, as at E', and works through an aperture in the bracket E2, which is supported on one of said upright posts A2. Said bracket surrounds and supports the paste-receptacle E2, adjacent to the lower ou tlet end of which is mounted a paste-roller E, and a pawl E5 of any ordinary construction may be secured to a projecting portion'of said receptacle and have its free end engage with the teeth ot a ratchet-wheel at the end of the paste-roller and prevent the latter from rotating in but one direction. This pasteroller may be given partial rotary movements bythe flaps of the bags coming in contact therewith.

Mounted upon a cross-piece F of the machine is a carriage F', having side wings F2 and handle F2. Said carriage has integral apertured lugs F4, which slide on the crosspieces F. The forward ends of the flanges F2 are bent at right angles, as shown at F5, and taper from their upper ends toward the bottom of the carriage, as shown clearly in Fig. 15 of the drawings. Behind said angled flanges the paper bags F6 are adapted to be held in vertical positions, as shown clearlyin the drawings, with their flaps away from the seed-filling tube. The outer of said bags is supported by the forward projecting end f of the handle F3 and by the spring-actuated member F7, mounted in the base portion of the handle. Pivotally connected to the rear end of said carriage is a link G,'having an elongated slot G' near its outer end, in which a lug D4, mounted on the lever D, is adapted to travel and by striking against the opposite ends of said slot cause the carriage to travel in opposite directions.

II is a lever which has pivotal connection with the pin a at its angled portion, also pivotal connection with the leverD at a location slightly above the pivot a, as at II'. Said lever H has pivotally connected to its opposite end a link H2, which in turn is pivotally connected to the ends of a collar H3, which collar surrounds and is fastened to the tubing E, as at H, whereby as the lever D is tilted on the pivot a. the tubing E is raised and lowered over the inner seed-tube B.

Mounted on the platform A is a standard I, upon which a pulley I' is mounted, and passing over said pulley is a rope I2, having a weight Ia at its lower end, while its opposite end passes through and is held by a projecting lug on the handle F2, as shown at I4. This weighted connection with the handle is provided for the pu rpose of advancing slightly the pile of bags and holding the same so that the forward one ofsaid bags will be held against the inner faces of the flanged ends F on the carriage in readiness to receive the lower end of the seed-introdueingspoutas the latter is depressed and by so doing opens the bag in readiness to receive the seed.

Pivotally mounted upon the main operating-shaft C are levers J, which have a rocking motion on said shaft, said motion being imparted by connections with the lever D. The upper ends of the levers J have pivotal connection with the links J', the outer ends of which are pivotally connected to the lower end of the clamping member K at K'. Said clamping member K is pivoted to the project-ing ends L of the rack L'. (Shown in detail in Fig. 12 of the drawings.) Said rack has an upright solid portion L2, having rightangled flanges L3 at its ends, and said rack has longitudinal flanges L4 on its outer faces which are adapted to slide in grooves in the table A.

The connections between levers J and D, before referred to, consist of the rods M and M', an enlarged detail view of which is shown in Fig. 13 of the drawings. Said rod M has pivotal connection at its forked end M2, Fig. 13, with the lever D and telescopes within the hollow portion of the rod M' and has alongitudinal movement within said hollow portion equal to the length of the slots M3, the ends of which serve as stops to the bolt N3, which is mounted on a collar N2 and which passes through the solid portion of the rod M. Interposed between said collar N2 and the nut N', mounted on t-he rod M', is a coiled spring N. This spring is provided for the purpose of allowing the rod M to have a slight longitudinal movement with the lever D for the' purpose of raising the lower beveled end of t-he tube E from the bag which rests upon the sliding rack, so that the clamping member K will not interfere with the lower end of said tube when said clamping member is thrown frictionally against the bag to hold it to the rack as the rack is carried forward to the position in which the flap-folding member is brought into play. After the bolt carried by the rod M strikes against the end of the slot nearest to the levers J it will be observed that the two rods M and M (the latter of which has pivotal connection with a T-rod M4, extending between the two levers J and shown in side elevation in Fig. will serve the purpose of a single rod for advancing the levers J, which will cause the clamping member K to contact with the bag and advance the same with the rack to positions underneath the paste-roll and bring into play the gear mechanism which will cause the flap to be folded.

Mounted horizontally on one of the uprights A2 is a rack-bar 0, having rack-teeth 0' on its upper edge, and mounted in the integral arms L5 of the upright L2 is a shaft O2, on one end of which is mounted a pinionwheel O3, which is adapted to mesh with the teeth of the rack-bar O as the carriage carrying said pinion-wheel is worked backward and forward. Integral with said shaft O2 is an offset or cam portion O, which is flat on IOO IIO

one edge and provided with a curved surface being clearly shown in the detail views of they drawings.

In order to hold the bag on the rack upon which it has been depressed from e carriage as the telescoping tube E'reaches its lowest limit and commences to return, I have provided a flexible arm E, (shown clearly in Fig. 1 of the drawings,) which arm is held to any stationary part of the frame, being Ilexithrough the tubes and into the ble, and, if desired, may have a rubber at its free end, which sweeps against the outer face of the bag as the latter is depressed to said table, and after the upper end of the bag passes said arm the free end thereof will project above the bag and prevent the same from being lifted with the telescoping tube E as it returns to its starting position.

In operation the seed is fed from the hopper by means of the reciprocating block A5, which carries the seed which has fallen by gravity in the aperture A6 on the cross-piece As forward to a position over the upper I'laring end of the feeding-tube B. As the block A5 is fed forward by the tilting of the lever D it will be observed that the outer telescopng tube E will be depressed and the lower tapering end of the seed-tube will enter a bag, which is shown in Figs. 1 and 2 of the drawings opening said bag. As the lower end of the tube enters the bag the aperture in the sliding block A5 will have reached the aperture registering with the upper flaring end of the tube B and the seed will fall bag underneath the lower ends thereof. When the lower end of the telescoping tubing reaches a location adjacent to the upper face of the carriage F', it will be observed that the lug D, carried by the lever D, will strike against the outer end of the recess in the link G and cause the carriage to be drawn backward slightly ing-tube E which enters the foremost of the bags to clear the front edges of the carriage as it lowers with the bag being filled to the block on which the standard I is mounted and on the opposite sides of which block the rack L is adapted to reciprocate. As the bag is depressed with the filling tube the weight Is and the spring-actuated member F7 will cause the presser-block having handle F3 to push the bags forward, so that the outermost thereof will contact against the inner faces of the flanges F5 of the carriage, as shown in Fig. 1,5. It will be observed that the presserblock and carriage have movements independent of each other. After the seed has been depressed in the bag and the bag lowered a suicient distance to allow the fill-k to the position shown in Fig. 2 of the drawings, on the return movement of the telescoping tubingE the clamping member K is thrown against the outer face of the bag and holds the latter against the uprights L, said clamping member being thrown so as to frictionally hold the bag in an upright position. The bag being thus held and as the tubing Es returns to its starting position, the lower end of the lever D will force the rod M forward until the shoulder of the forked member M2 strikes the end nut N on the end of the rod M', after which the two rods M and M will move together and force the lever J forward and with it the carriageL' and connecting-link and clamping member. As the iap ofthe bag passes underneath the paste-roller E4 said fiap will be coated with paste preparatory to its being folded against the bag. As the pinion-wheel carried by the carriage L comes into mesh with the teeth O it will be observed that the olset or cam portion O4 will begin to rotate with the shaft on which the pinion is mounted and against the flap, turning the latter successively into the positions shown in detail views, Figs. 6 to 9, inclusive. After the cam portion O* has reached its farthest outward limit, in which the pasted iiap is held tightly against the face of the bag, the tube E will have reached its highest limit and the bag will be in readiness to be deposited from the machine. On the outer swing of the lower end of the lever D the spring N will contact slightly, which will cause the clamping-member K to be released from the bag and allow the latter to fall by gravity, as shown in Fig. 11 of the drawings. As the lower end of the telescoping tube E enters the bag it will be observed that the outer face of the bag near its upper open end will be contracted, which will allow the bag to pass freely by the inclined angled anges F5, (shown in Fig. 13 of the drawings,) and in order to force the bottom portion of each bag forward to the edge bf .the carriage the springactuated block or member F7 comes into play. On the return movement of the carriage which has carried forward the lilled bag to be pasted and folded it will be observed that the oset or cam portion of the shaft will return to its starting position and be in readiness to receive the next bag.

From the foregoing it will be noted that the various movements in my improved bag-filling machine are all automatic, the movement of each part being previously determined, so that the various parts will accomplish the desired end without interfering with one another.
